He said Metgasco is ignoring overwhelming community opposition to the CSG project, and it is in for a stand-off.

"I always approach direct action of this sort with trepidation because it's not what you'd prefer to do,' he said.

"You'd prefer this whole area of public policy to have been dealt with properly by government.

"It hasn't been.

"So it's really up to the community then to dig their heels in.

'While I'm cautious about doing this sort of blockading I think it's the only thing that will force government to adopt a sensible and rational public policy."

Mr Hutton said he will join the protest action today.

"This is a significant action," he said.

"This is an attempt by Metgasco, the most active of the coal seam gas companies in the Northern Rivers, to force their way onto a property despite the overwhelming opposition from the community.

"This is a real stand-off and it's an important confrontation.

"But it'll be a confrontation that's repeated time and time again if the industry and if the government wants to continue in this fashion."

Metgasco said the blockade of its Glenugie well site is an overreaction.

Managing director Peter Henderson said the work has state government approval and landowner consent.

He said much of the local opposition to coal seam gas is based on misinformation.

"We think when people know the full truth about coal seam gas and what it can provide, the fact it's safe, we will get support from the entire Northern Rivers region as well as the bigger community of NSW," he said.

"We are legally entitled to be there, we have the support of the state government, the community has not been ignored."
